Priapulida. (From Barnes 1987
after Hyman 1951)
Priapulida phylum of only 17 known species of the Aschelminthes. Cucumbershaped or worm-like animals living buried in the sea bottom. The animals
consist of a spiny proboscis (one-third of the body) for catching soft-bodied
prey, and a posterior part or trunk. They live in soft bottoms in colder seas
of the northern hemisphere.
primary production ~production.
primary wave ~P-wave.
Prince Albert I of Monaco Expeditions (1885-1914) almost annually Prince Albert I
made voyages in the Mediterranean and the Atlantic with his different
research ships, the Hirondelle I and II and the Princesse A/ice I and II. Drift
bottles were set adrift at different positions in the Atlantic Ocean to study
the Gulf Stream. A large series of monographs deals with the biological collections made. For the first time baited traps were used to collect deep-sea
scavengers. Prince Albert also founded the Musee Oceanographique in Monaco in 1910, a research center where the biological collections made could
be studied; it also has an excellent collection of historical oceanographical
instruments.
prions (1) small proteins apparently self-replicating but completely devoid of
nucleic acid. ~virus; (2) group of, particularly Antartic, sea birds.
proboscis tubular process of the head, used in feeding, burrowing, or locomotion.
procaryote ~prokaryote.
